To all whom it may comment:

Be it known that I, HIPPOLYTE ROMAN on, a subject of the Em eror ofRussia, and n resident of St. Peters )urg, Russia, (my postofiiceaddress being 22 Fontankn, St. letersburg,) have invented certain newand useful Improvements in Single-Rail Electric Overheed Railways withSuspended Vehicles of which the following is a specification.

This invention relates to an improved eonstruetion in eleetriesingle-rail overhead railways with suspended vehicles.

The invention has for its ohjeet to ohtiiin in railways of this kind thegreates possihhsecurity against derailment. This is etfected by thepeculiar construotion oi the Wheel-frames and the manner in whi'oh thevehicles are suspended, so that the rollingstoek can only becomederailed on the shunttaneous frertnre of several parts of the movablewheel-Frames. At the same time the propulsion of the wheel-frames iselieeted hy a comparatively small propelling force, as therunning-wheels have no ilenges and are constructed with special elastictires, whereby the detrimental 'i'riotion of the wheel -tire against therail is prevented and the (ZOIICUSF sions are roduoed. Lastly, theeleotromotor employed is of such construction that for operating thesame only a comparatively sinnil amount of electrical energy isrequired, so that the weight of the motor can he kept comperetivelysmell.

The improved construction is shown on the accompanying drawings.

Figure 1 shows 'a side View of the overheadrailwev with the suspendedvehi: to. his. 3, an end view thereof; Fig. 3, an end view of part ofthe wheoldreniep Fig. 4, the same view of the wheel-frame, but with'iinnltcrvd inclinednn'engement of the guide-rollers; Fig. 5, a side view ofthe wheel-frame Fig".

The railway rests, hy means of st :indnrds 1. upon the foundation 1 andconsists of trnnsverse hearers 3 and of longitudinnl girders 4 fixed tothe letter. ()11 the upper llnlne'o oi the girder is fixed the rail 5,Figs. 3 and 4. ()n the topolthe mil 5 run t he (lliVlliI-Wl10iilS 16and. runnirig-wheels in of tho n'lHl'l-ll'ztl'fit end at the sidestin-root" the lnn'izontiil or in- 'ined uide rollers 7, which serve toprevent the deruiline oi the \vhooi-hmnes. To the hotloni (hinge oi thegirder 4 is riveted a troziglnslmped lir-ann R, the side llztnges otwhi-h scrx o as guides for t he lower horizontal side ro h rs t) of thewherl-t'rinne. The rnii 5 is lixrd to iln girder Iiy moons of rhilnps 1tand lmlts ti and together with the bottom lllttln S greatly iiurmisesthe strength and safety of the girder.

The vohiole is suspended from two wheelframes, each of which tonsists ofon upper frame 12, Figs. .3. 4, and 5, and a. lower route 13. The upperframe 12 is carried h the hearings 1%,in whizh the axles l5" oi therunning-wheel to and the axles 1.5 of the inotorwheels 6 run. Each axle15 15 has two hearings H. In the ronstrlu-ti-ni shown ear h whool-irinnorontnins four axles l5 and 1.3. ()n the axles 15 are lixod the(l(..lI(ln'mtors l8. The whevt-l'rnme would, however, he provided withit dill'ervnt nnmher of l axles and heels in writing! t(llltilllslttZlUtS. To the upper irznno ll? :n'rriveted at top and athottoni lseiweln the heels troughshnped stool lnzuns it) n ifh openingslhr the passage of the stool lnn's it).

The lower i'rn rc l3 onstitutes :1 box shaped l'rzin'e and also l ne:openings for the passage of the lower ends of the Inn's 20. which arescoured h screw-nuts '21, us are also the upper ends. The hers 20, Fig.:3, are so arranged that sour ol tl'ein are sitn ated near to therail-girder, "while otl 01's tll't' situated further away. The objectoftlhi is to render the entire system strong: and light as the vohirlesuspended from the lower Frame tends to bond asunder the wheellltl-Zttt,which is oi :tn open-loop shnpo, so thnt the hairs nearer theroll-girder are subject to e. tensions] strain, ul-ilo those situatedinrthernweynrrsnhjcrled to minprcssion. On this HtKtflllIll' tho hersitunted l'nrthernnny from the girder are intnle oi snniller diameter andinelosed in steel tubes 22, whieh serve as distnnecepirres and stru tsbetween the upper and lower to ours. For reducing the notion n pen thehermit), caused in; the lateral stmins, diagonal ties are provided.lying in the same plane with. the liars 30 and suhjcrt to .1. tensionnlstrain. In the oonstrnrtion shown ouch \vlieel-iriitne has three hairs20 end two struts 32, each her and strut. living so t-eloib lnted us tohe enpzihle of supporting the weight of the vehicle and its lond, sothat the wheel-ironic can support at multiple ol the ire-- tusl load.

l l l l For maintaining the ecniilihriuni of the wheehfranie upon theline of ruil in the obsence of hinges on the wheels the up )0! and lowerfrom es are provided with lateral rollers 7 and 9. which bear,respectively, upon the side surfaces of the rail 5 and of thetroughshoped beam 8. There may be a greater or less number of the siderollers 7 and 2 new cording to cireun'istanccs. in the eons-truetionshown the wh eel-franie has tour rollers 7 and two rollers 9.

By re leeing the flanges of the wheels by means 0 horizontal or inclinedrollers 7 and 9 an arrangement provided by n1enns of which the line ofrailway is gripped at three points. The possibility of dera iling ol'the wheel-frame without the simultaneous {ructure of several of itsparts is therefore done away with. in addition, already anontioned, thefrictional resistenre cuud by the ordinary flanged wheels is obviated.

The suspension arrangement of the vehicle is constructed as follows Onthe lower frame 13, Figs. 7 and 8, of t he wheel-ironic is riveted abearing-ring 334 with yohe-piece 3.. The rings 34 have n eirculurgroove36, in which run steel balls 37, Upon the ring 34 lies a turn-table 38,which also has a circular groove corresponding to the groove 36. In themiddle of the turn-table 38 is formed an opening through which passesthe pin 3.) of a screw-bolt 40;; screwed into the yoke 35. Froln theturn-table 38 is Suspender by means of bolts 41,11 spring-freine 42,which has at its ends bmeshaped beun'is 43, that are connected to theframe by means of ribs 44. The spring-sup ort of the frame 42 iseflected by means 0 the helical springs 45 and 46, which bear againstthe box-beam 43 and are compressed, by means of bolts 47. with washers48. The up )er springs 45 are made stronger than the ower reguletingpsprings 46. To the side surfaces of the beznn 43 are fixed, by means ofthe bolts, (not shown on the drawings) steel rods, from which thevehicle is directly suspended.

For the propulsion of the wheel-frames electroinotors are employed, asshown at Figs. 9 and 10, the armature 49 of which fixed directly uponthe axle of the driving t wheel. The eloetronmgnets 50 are situatedwithin the armature and. are ilXLtl by bolts 51 to the bearings of thedriving-wheel axles. The eleetromotor has the weulinritr ti ii thearmature 49 has at ooieiderehly greater dinineter than the drivinwwneel,so that the peripheral velocity of the mess ol' the arinw ture exceedsthat ol the d'livilng-wlwel when running. The mass of the nrnnrture cantherefore be comparatively snntll For :1. eertnin propelling power, andconsequently the cleetroiuotor is of loss weight than with othereonstructirms. in addition the armature requires a less amount of energy['or propelling the vehicle in (-onsmpienre of its or enter turningmoment Lastly, the :tirert urtion oi the eleotronnitor upon the wheelswituout trnnsntissio'n-gezu enables it very econonirul eoiennnption olenergy to be at tuined.
